Recently replaced a 3845 in my Data Center with a ISR 4331. Used the same Fiber SFP that was in the 3845 in the 4331.
My network monitor is showing my WAN interface and completely down.
This is the output from the sh interface:
DALLAS-4331#sh int g0/0/0
GigabitEthernet0/0/0 is up, line protocol is up
Hardware is ISR4331-3x1GE, address is d0ec.35e5.xxxx (bia d0ec.35e5.xxxx)
Description: <== Connection to CenturyLink MPLS ==>
Internet address is xx.xx.182.102/30
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not supported
Full Duplex, 1000Mbps, link type is force-up, media type is LX
output flow-control is on, input flow-control is on
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output 00:00:11, output hang never
Last clearing of "show interface" counters never
Input queue: 0/375/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: Class-based queueing
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicasts)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 watchdog, 0 multicast, 0 pause input
4532 packets output, 500098 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 unknown protocol drops
0 babbles, 0 late collision, 0 deferred
6938 lost carrier, 0 no carrier, 0 pause output
0 output buffer failures, 0 output buffers swapped out
Insights as to where the issue lies? also the significance of the lost carrier packets.
The WAN interface was working properly on the 3845.
Even though the router is unavailable via WAN I am able to get to it via a secondary inter route.
